20100149865 | SCR MATRIX STORAGE DEVICE - One of the simplest forms of data storage devices is the diode array storage device. However, a problem with diode array storage devices is that as the size of the array increases, the number of non-addressed diodes connected between a given selected row or column of the array and the non-addressed columns or rows of the array, respectively, also becomes very large. While the leakage current through any one non-addressed diode on the selected row or column will have little impact on the operation of the device, the cumulative leakage through multiple thousands of non-addressed diodes can become significant. This aggregate leakage current can become great enough that the output voltage can be shifted such that the threshold for distinguishing between a one state and a zero state of the addressed diode location can become obscured and can result in a misreading of the addressed diode location. The present invention is a means to manage the leakage currents in a diode array storage device. This is accomplished by actively changing the forward voltage of the diodes in the storage array such that a diode connected to the selected row line but that is not connected to the selected column line is in its high impedance state and a diode connected to the selected column line but that is not connected to the selected row line is in its high impedance state; only a diode that is connected to both the selected row line and the selected column line will switch to its low impedance state.
